But only as far as I say "create new layer/image with white
background"... Or, wait, are you suggesting that "filling" is an
operation known to GEGL, so a SolidFilledLayer will just change it's
fill_color when it get's filled again?
After all, this optimization does not work any more if I fill an
arbitrary selection...
